the research was aimed at finding out the effects of the implementation of writing feedback techniques and students’ writing anxiety on students’ writing ablity. experimental method of 3x2 factorial design was employed in the research. there were three experimental groups of students who were taught by using teacher feedback, peer feedback and the combination of peer and teacher feedback writin...

We introduce a method for the specification of reactive asynchronous components with a concurrent access interface and outline its mathematical foundation. The method supports the specification of components that show a complex reactive behavior including timing aspects. Examples are the nonstrict fair merge or the arbiter. The method supports the specification of reactive systems and their mod...

In this paper, we propose separation set partitioning algorithm for partitioning nonstrict programs into threads using participation set and separation set and extened it to global partitioning. Separation set partitioning algorithm can merge threads which dependence set and demand set partitioning algorithm may fail to merge. It deals with certain indirect depdendences and potential indirect d...

based on the controversial beliefs among l2 teachers about effective corrective feedback (cf) strategies, recast and prompts as 2 kinds of cf have drawn the attention of l2 researchers(e.g., braidi, 2002; iwashita, 2003; loewen & philp, 2006; panova & lyster, 2002; sheen, 2004). despite these numbers of studies, debate continues to exist about their usefulness as a cf technique. whereas...

time-delays are important components of many dynamical systems that describe coupling or interconnection between dynamics, propagation or transport phenomena, and heredity and competition in population dynamics. the stabilization with time delay in observation or control represents difficult mathematical challenges in the control of distributed parameter systems. it is well-known that the stabi...

This paper analyzes conformist tendencies for a population in which individuals gain utility by mimicking the average behavior, characterizing norms by the mean behavior. In so doing, the model extends Bernheim (1994)’s “A Theory of Conformity” by introducing an endogenous mechanism for establishing social norms. The most interesting result is that this extension does not alter the properties o...
